Make use of the new drivers for ARM U8500 introduced in the U-Boot
2021.10 merge window by adding basic support for USB Fastboot with
the "stemmy" board. As a first step this will always boot directly
into USB Fastboot for now with the console displayed on the screen
to make that obvious.
Samsung uses quite strange GPT partition labels on these boards,
so also add a bunch of fastboot_partition_alias_* to make this more
easy to use.

So far there is no need for a clock driver in U-Boot because the
previous boot stage leaves all the necessary clocks on. However,
some drivers in U-Boot (e.g. arm_pl180_mmci) depend on having a clock
driver to obtain the clock frequency.
Setting up the clock drivers properly is a bit tricky on U8500,
so for now add a simple fixed-clock for the eMMC that allows obtaining
the clock frequency. This should be replaced eventually if some board
actually requires enabling some of the clocks.

Update ste-dbx5x0.dtsi, ste-ab8500.dtsi and ste-ab8505.dtsi with
the changes made in upstream Linux. They are taken from
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik.git/
branch "ux500-dts-for-v5.15" (pending merge for Linux 5.15).
The only relevant change for U-Boot here is
"ARM: dts: ux500: ab8500: Link USB PHY to USB controller node" [1]
which links the USB PHY to the USB controller. This is necessary on
U-Boot because the PHY driver is implemented as part of the generic
PHY subsystem that makes use of these bindings.

Currently, an empty imput file causes `mmap()` to fail, and you get an
error like "mkimage: Can't read file.img: Invalid argument", which is
extremely unintuitive and hard to diagnose if you don't know what to
look for. Add an explicit check for an empty file and provide a clear
error message instead.
We already bounds check the image size when listing and re-signing
existing images, so we only need this check here, when opening data

Older OpenSSL and libressl versions have a slightly different API.
This require #ifdefs to support. However, we still can't support it
because the ECDSA path does not compile with these older versions.
These #ifdefs are truly a vestigial appendage.
Alternatively, the ECDSA path could be updated for older libraries,
but this requires significant extra code, and #ifdefs. Those libraries
are over three years old, and there concerns whether it makes sense to
build modern software for real world use against such old libraries.
Thusly, remove #ifdefs and code for old OpenSSL and LibreSSL support.

A rather common kind of external watchdog circuit is one that is kept
alive by toggling a gpio. Add a driver for handling such a watchdog.
The corresponding linux driver apparently has support for some
watchdog circuits which can be disabled by tri-stating the gpio, but I
have never actually encountered such a chip in the wild; the whole
point of adding an external watchdog is usually that it is not in any
way under software control. For forward-compatibility, and to make DT
describe the hardware, the current driver only supports devices that
have the always-running property. I went a little back and forth on
whether I should fail ->probe or only ->start, and ended up deciding
->start was the right place.
The compatible string is probably a little odd as it has nothing to do
with linux per se - however, I chose that to make .dts snippets
reusable between device trees used with U-Boot and linux, and this is
the (only) compatible string that linux' corresponding driver and DT
binding accepts. I have asked whether one should/could add "wdt-gpio"
to that binding, but the answer was no:
https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/
If someone feels strongly about this, I can certainly remove the
"linux," part from the string - it probably wouldn't the only place where
one can't reuse a DT snippet as-is between linux and U-Boot.

A board can have and make use of more than one watchdog device, say
one built into the SOC and an external gpio-petted one. Having
wdt-uclass only handle the first is both a little arbitrary and
unexpected.
So change initr_watchdog() so we visit (probe) all DM watchdog
devices, and call the init_watchdog_dev helper for each.
Similarly let watchdog_reset() loop over the whole uclass - each
having their own ratelimiting metadata, and a separate "is this device
running" flag.
This gets rid of the watchdog_dev member of struct global_data. We
do, however, still need the GD_FLG_WDT_READY set in
initr_watchdog(). This is because watchdog_reset() can get called
before DM is ready, and I don't think we can call uclass_get() that
early.
The current code just returns 0 if "getting" the first device fails -
that can of course happen because there are no devices, but it could
also happen if its ->probe call failed. In keeping with that, continue
with the handling of the remaining devices even if one fails to
probe. This is also why we cannot use uclass_probe_all().
If desired, it's possible to later add a per-device "u-boot,autostart"
boolean property, so that one can do CONFIG_WATCHDOG_AUTOSTART
per-device.

While here, clean up the preprocessor conditional: The ->watchdog_dev
member is actually guarded by CONFIG_WDT [disabling that in
x530_defconfig while keeping CONFIG_WATCHDOG breaks the build], and in
the new world order so is the existence of the wdt_stop_all()
function.
Actually, existence of wdt_stop_all() depends on CONFIG_${SPL_}WDT, so
really spell the condition using CONFIG_IS_ENABLED, and make it a C
